Title: Direct contact type methanol fuel cell
Inventor: HITOMI SHUJI
IPC: H01M8/06
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of output due to the crossover of methanol of a negative electrode with a positive electrode, and provide stabilized high output for a long time by using a catalyst, which selectively and electrochemically reduce oxygen, for positive electrode, and using a catalyst, which electrochemically oxidizes methanol, for negative electrode. SOLUTION: A positive electrode is provided with a catalyst formed of carbon carrying gold and silver, which selectively and electrochemically reduce oxygen, or an alloy having at least one of gold and silver, or the mixture thereof, and a negative electrode is provided with a catalyst, which electrochemically oxidizes methanol, so as to form a direct contact type methanol fuel cell. With this structure, even in the case where a crossover that methanol as a fuel of the negative electrode is moved to the positive electrode as an opposite electrode through the electrolyte is generated, since the catalyst of the positive electrode is inert to methanol for electrochemical oxidization, the only electrochemical reduction of oxygen is performed, and electrochemical oxidization of methanol is not performed. Lowering of output due to the crossover is thereby prevented.

Abstract: PURPOSE:To prevent reduction of the thickness of a field oxidized film due to etching and obtain the device of high performance by a method wherein a coating film of Si3N4, Al2O3, poly Si or the like having a selective etching property in relation to an SiO2 film on an island area surrounded by the field oxidized film is provided on the field oxidized film. CONSTITUTION:SiO2 102 and Si3N4 103 are laminated on P<-> type Si, resist 104 is applied thereon, etching is made, and thereby a mask 103' is prepared. After injection of B ion, wet oxidization is applied, thereby a P<+> inversion preventing layer 106 and the field oxidized film 105 are provided and Si3N4 3' is removed by plasma etching. Next, an Si3N4 mask 107 is applied onto SiO2 105 and SiO2 105 is exposed in the end part, whereby SiO2 102 is removed through etching. Then, SiO2 111 and poly Si 110 to which phosphorus is added are formed afresh selectively and subjected to wet oxidization to form SiO3 113 and further poly Si 114 to which phosphorus is added is prepared selectively through the intermediary of SiO2 115. After that, an n<+> layer 116 is provided and covered with SiO2 115, to which an electrode 118 is attached. By this constitution, the reduction of the field oxidized film due to etching in the course of processes is prevented and thus sufficiently high field-inversion voltage is ensured.

Title: Method of furnace pressure control
Inventor: MIURA IKUO
IPC: F23G5/50
Filed: 1984-08-20
Abstract: PURPOSE:To surely prevent the furnace pressure from becoming a positive pressure in an incinerator of urban rubbish etc. by determining whether the detected furnace pressure is higher or lower than the set value, and, when the detected value is higher than the set value, making the gain of the control system larger than that gain which is obtained when the detected value is lower than the set value. CONSTITUTION:The furnace pressure of an incinerator 1 becomes the output PV1 via a pressure transmitter 10 and a primary delay filter 15. By a subtracting unit 16, the difference from the set value SV of a PID adjusting unit 11 is determined. By an input compensation nonlinear arithmetic unit 17, when SV< PV1, a gain larger than which is obtained when SV>PV1 is selected to output PV3. In response to the output PV3, the PID computation is conducted in the PID adjusting unit 11 to output MV1, and the output MV0 is outputted via an adding unit 20. As the actuating output MV0 has become larger when SV<PV1 than when SV>PV1, the actuating speed of the damper 4 is made higher by the output MV0, the furnace pressure is promptly prevented from being increased to become a positive pressure.

The order of 0-3 depending upon writing operation is stored and calculated by an unshown CPU and compared with the contents of a pattern memory Individuals set their reference patterns in the pattern memory by placing the CPU in setting mode. For example, ''7'' corresponds to ''3013''. Consequently, differences among individuals are absorbed to identify characters easily and precisely.

Title: Evaluation method and design method for fluidity analysis of mold for synthetic resin injection molding
Inventor: SASAKI YASUHIRO
IPC: B29C33/38
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce time and costs to obtain an optimum mold for synthetic resin injection molding by comparing the position of a weld obtained by the first prediction calculation with the thickness of a solidified layer obtained by the second prediction calculation. SOLUTION: The position of a weld is prediction-calculated (step 1) and image-output on a display (steps 2, 3). The output images are overlapped and compared, and the thickness of a solidified layer predicted at the position of the weld is obtained (step 4). The conditions of the mold are regulated so that at the position of the weld which was obtained by the first calculation, the thickness of the solidified layer obtained by the second calculation becomes a prescribed value or less. When the thickness of the solidified layer at the position of the weld is judged to be greater than a prescribed value (step 5), the generation of a visible weld line at the position of the weld is considered possible (step 8). In this case, data are changed, and the steps 1-4 are repeated until the thickness of the solidified layer becomes a prescribed value or less.

Abstract: PURPOSE:To obtain easily an electrode having an arbitrary circuit pattern, by performing etching while a voltage is applied using a transparent conductive film as an anode, after the transparent electrode whose main component is indium oxide is formed on a substrate. CONSTITUTION:A transparent conductive film is formed on a glass substrate by high frequency sputtering method applying a material wherein indium oxide and aluminum fluoride are mixed with a weight ratio of 95:5 and sintered.

Abstract: PURPOSE:To drive a lens at a speed corresponding to depth by providing the power focus device with a settlement circuit which settles a lens driving quantity corresponding to the manipulated variable of an operation member according to a factor determining depth-of-field information or depth. CONSTITUTION:In power-focus mode, the driving quantity corresponding to the manipulated variable of the operation member is settled according to the depth information.

Consequently, focusing is facilitated even when it is difficult to put the lens in focus with a manual focus ring.
